A kind of multielement alloy cast ball quenching medium
Technical field
The present invention relates to heat-treatment quenching technical field, refer more particularly to a kind of multielement alloy cast ball quenching medium.
Background technology
Quenching is to make metallic substance obtain an important means of affiliated performance, and quenchant is one of key factor obtaining high quenching quality.Flourish along with petroleum industry, in 20 beginnings of the century, mineral oil starts to be used to quench cooled.Mineral main body of oil is stable hydrocarbon, and performance is relatively stable, so be widely used.For improving the cooling performance of mineral oil, people develop again and the quenching oil that contains various additives that is base to mineral oil, remain the quenchant of main use.Yet mineral oil quenching medium causes severe contamination to environment, mineral oil flash is lower, in quenching process, forms dense smoke fire-prone, this danger aggravation greatly especially while containing water in oil.The degradation property of mineral oil is very poor, so discarded mineral oil is just very large to the potential threat of the pollution of environment.Investigation discovery, the mineral oil of discarded discharge is the primary pollution source of underground water.For improving quenching oil performance, many surfactant-based additives have been added.Most of additives have all strengthened the difficulty of liquid waste disposal, as the additives such as compound of baric, or potential carcinogenic substance, the environmental hazard that has further strengthened mineral oil quenching medium.Existing increasing enterprise abandons using oil quenching when thermal treatment in recent years, and adopt various water-soluble polymer organic aqueous solutions, is the heat-eliminating medium that steel alloy quenches.Yet, although the water-soluble organic cooling medium of this class does not produce severe contamination and does not have disaster hidden-trouble while being used for quenching, but market price is still very high, and, the former media storage phase is limited, after user buys, also separately needing to be mixed with by a certain percentage voluntarily the aqueous solution could use, and in use, organic solution after heated can accelerated deterioration, its cooling characteristic is changed, as changed not in time, will make Ways of Heat Treatment Product Quality decline, even unqualified.
Summary of the invention
